# Compound Interest Calculator - Getting Interest On Interest

Use the Compound Interest Calculator to determine how much money you would accumulate by investing a given amount of money at a fixed annual rate of return for a specified period in years.

For example, if you invested $1,000 at a 5 percent annual rate of return, after 10 years you would have $1,628.89.

## Computational Notes:

The future value is computed using the following compound interest formula:Future Value = Investment Amount * (1 + Annual Rate of Return / 100) ^ Number Years
